ABSTRACT

The investigation reveals the adoption of method Performic Acid – Alcian Blue yields a good positive result of the cerebral ganglionic neurosecretory elements of Lymnaea (Radix) luteola exposed to various temperatures. Incidentally a good positive intensity of the stain is being elicited when the animals are kept in the different fluctuating temperature regimes ([low (4°C, 10°C), near ambient (20°C, 25°C) and high (30°C, 35°C)] on their secretory dynamics. Side by side, the histochemical nature of the neurosecretory material has also been recorded. In all the profiles of study individuals exposed to near ambient temperature are being considered as normal. And finally, the histochemical analyses are made under different temperature regies on the cerebral neurosecretory elements to ascertain correlative biochemical changes.
